Question

The African bush elephant weighs between 4.4 tons and 7.7 tons. What are the least and greatest weights of 3 elephants, rounded to the nearest ton

Answer 1

least = 13 tons

greatest = 23 tons

Reason

The smallest an elephant can weigh is 4.4 tons.

Three such elephants weigh at minimum 3*4.4 = 13.2 tons. This rounds to 13 tons.

Also, three elephants weigh at most 3*7.7 = 23.1 tons. That rounds to 23 tons.

The span of weights is from 13 tons to 23 tons, when rounding to the nearest ton.
